A facile approach to polymethacrylate networks that contain thermally exchangeable bis(2,2,6,6-tetramethylpiperidin-1-yl)disulfide (BiTEMPS) cross-linkers is reported, and the easily inducible healability and reprocessability of the obtained networks are discussed. The free radical polymerization of BiTEMPS cross-link…
In these years a variety of polymeric nanocarriers such as dendrimers, polymeric micelles, nanoparticles, nanogels, nanocapsules and vesicles are widely investigated as potential drug delivery systems. In addition to the different morphologies and sizes, these carriers may have on their surfaces specific functionaliza…
Chitin nanocrystals (CNCs), rod-like crystalline nanoparticles from natural sources, show high aspect ratio, high modulus, and excellent reinforcing ability toward polymers. In this study, CNCs aqueous dispersions were first prepared by acid hydrolysis of raw chitin. The resulting dispersion was investigated by polari…
The dispersion of ferroelectric nanomaterials in liquid crystals has recently emerged as a promising way for the design of advanced and tunable electro-optical materials. The goal of this paper is a broad overview of the current technology, basic physical properties, and applications of ferroelectric nanoparticle/liqu…
We report considerable improvement in the hysteresis and reliability of single-layer MoS2field-effect transistors (FETs) achieved by chemical vapor deposition (CVD) of MoS2and dielectric encapsulation. Our results show that a high-quality 15-nm thick Al2O3layer allows for an efficient protection of the devices from ad…
Abstract In this study, we report the efficacy of RGD (arginine-glycine-aspartic acid) peptide-modified polylactic acid-co-glycolic acid (PLGA)-Chitosan nanoparticle (CSNP) for integrin α v β 3 receptor targeted paclitaxel (PTX) delivery in lung cancer cells and its impact on normal cells. RGD peptide-modified chitosa…
Proteins encountered in biological and environmental systems bind to engineered nanomaterials (ENMs) to form a protein corona (PC) that alters the surface chemistry, reactivity, and fate of the ENMs. Complexities such as the diversity of the PC and variation with ENM properties and reaction conditions make the PC popu…
In this work, mesoporous TiO 2 spheres supported MnCeW mixed oxide catalysts (MnCeW/m-TiO 2 ) for selective catalytic reduction of NO x with NH 3 were prepared by a wet impregnation method. It is interesting that the MnCeW/m-TiO 2 catalysts exhibited excellent SCR activity and N 2 selectivity in a wide temperature ran…
All crystalline materials in nature, whether inorganic, organic, or biological, macroscopic or microscopic, have their own chemical and physical properties, which strongly depend on their atomic structures. Therefore, structure determination is extremely important in chemistry, physics, materials science, etc. In the…
Abstract: Due to the widespread applications of zinc oxide nanoparticles (ZnO NPs), the potential exposure of workers, consumers, and scientists to these particles has increased. This potential for exposure has attracted extensive attention in the science community. Many studies have examined the toxicological profile…
A nonlinear two-dimensional (2D) continuum with a latent internal structure is introduced as a coarse model of a plane network of beams which, in turn, is assumed as a model of a pantographic structure made up by two families of equispaced beams, superimposed and connected by pivots. The deformation measures of the be…
In this work, a microwave welding method has been used for the construction of chemical Ni-C bonding at the interface between carbon nanotubes (CNTs) and metal Ni to provide a different surface electron distribution, which determined the electromagnetic (EM) wave absorption properties based on a surface plasmon resona…
Prosthetic arteriovenous grafts (AVGs) conventionally used for hemodialysis are associated with inferior primary patency rates and increased risk of infection compared with autogenous vein grafts. We tissue-engineered an AVG grown from neonatal human dermal fibroblasts entrapped in bovine fibrin gel that is then decel…
Chemotherapy is still one of the main cancer therapy treatments, but the curative effect of chemotherapy is relatively low, as such the development of a new cancer treatment is highly desirable. The gradual maturation of nanotechnology provides an innovative perspective not only for cancer therapy but also for many ot…
Excitons dominate the optical properties of monolayer transition metal dichalcogenides (TMDs). Besides optically accessible bright exciton states, TMDs exhibit also a multitude of optically forbidden dark excitons. Here, we show that efficient exciton-phonon scattering couples bright and dark states and gives rise to…
Recently discovered two-dimensional (2D) boron polymorphs, collectively tagged borophene, are all metallic with high free charge carrier concentration, pointing toward the possibility of supporting plasmons. Ab initio linear response computations of the dielectric function allow one to calculate the plasmon frequencie…
High Resolution Image Download MS PowerPoint Slide Conventional chemical oxidation routes for the production of graphene oxide (GO), such as the Hummers’ method, suffer from environmental and safety issues due to their use of hazardous and explosive chemicals. These issues are addressed by electrochemical oxidation me…
Covalent organic frameworks with hydroxy groups in the pore wall, which exhibit efficient, metal-free, heterogeneous catalytic performances for chemical fixation of CO <sub>2</sub> under mild conditions, are reported.
Fashion Technology & Textile Engineering introduces pioneering technologies, and improved understanding of textile materials, processes, chemistry and systems. It will encourage interdisciplinary research which will share newly developed technology, theory and techniques in the fashion and textile
Rare-earth-based pnictide oxides ( RE,Ca) m Pn n O m ( Pn = Sb, Bi) adopt a variety of interrelated structures based on specific stacking sequences of rare-earth oxide sublattices. These phases are all prepared via high temperature reactions and may be selectively produced in high purity. X-ray single crystal studies…
